Alvotech has just become the first company to announce positive topline results from a confirmatory clinical study for a proposed golimumab rival to Simponi and Simponi Aria – and moreover, the firm sees limited competition from other biosimilars on the horizon.

After getting off to a slow start last year, US biosimilar rivals to Humira are beginning to gain more traction. Sandoz is increasing its share on a weekly basis, Alvotech and Teva have struck a deal for their newly-approved interchangeable 100mg/ml biosimilar, and the latest market data shows biosimilars capturing twice as much of the market in Q1 as in Q4 2023.

US market access senior VP Tom Rainey talks to Scrip about the upcoming launches of biosimilar versions of Humira and Stelara.

Alvotech’s high confidence for FDA approval for its Stelara biosimilar has been justified, as the Icelandic firm announced only the second US approval for a rival to J&J’s Stelara powerhouse brand, ahead of market formation in 2025.
